Ambient conditions during operation Temperature ( C)...+5 to +40 Relative humidity (%)... max.80 Ambient conditions during storage and transport Temperature ( C) to +50 Rel.humidity (%)... max Functional description This appliance has been developed to aspirate secretions, blood, tissue and bone, as well as fluids accumulating during drilling, from the patient s oral cavitiy.this unit is especially recommended for mouth and mandible surgery, e.g.in implantology, where large amounts of blood are likely to be produced and which has a tendency to coagulate.conventional suction machines and/or separation units cannot usually cope. Both vacuum and delivery have been specially adapted for this special usage and can be regulated from the unit itself. After switching on the VC 45 at the main power supply switch, the vacuum pump in the unit starts up.on the upper side of the VC 45 there is a pressure gauge which displays the level of vacuum being produced.to regulate the vacuum, close the suction handpiece adjust the amount of vacuum required by turning the rotating thumb screw.once a surgical cannula has been inserted into the suction handpiece, the VC 45 is operational.the aspirated material passes directly to the collector vessel.inside the collector vessel, the air is separated from the aspirated fluids and other particles.within the collector lid there is a bacteria filter, which is designed so that fluids are prevented from flowing to the vacuum pump.below this bacteria filter there is a spray shield, which stops any fluids being splashed towards the bacteria filter.once work has ceased, the unit should be switched off at the main power supply switch. Before removing the collector vessel in order to empty it, be sure to allow a few moments for the vacuum pressure within the unit to subside /10

9 7. Set-up Installation 7.1 Room for set-up Medical treatment rooms or operating rooms. Room temperature must not fall below +5 C in winter and must not exceed +40 C in summer. If the appliance is first connected during winter months, allow sufficient time after transport and unpacking for the unit to warm to room temperature before initial operation.(danger of short circuit due to build up of condensation.) 7.2 Set-up alternatives Set up the VC 45 on a stable flat and raised surface next to the treatment unit. Operation of the VC 45 directly on the floor is not permitted Set up the VC on the special cart (available as special accessory) 8. Electrical Connection Before first use (during commissioning), check that the supply voltage is the same as that given on the model identification plate.

21 16. Preparation During disinfection and cleaning, it is absolutely vital that the valid accident prevention procedures for the surgery are observed (e.g. gloves, protective glasses, mouth protection) The measures described concerning disinfection and cleaning or sterilisation in no way replace the surgery rules and regulations. Before treating every patient, check that the following parts have been sterilised: - suction hose including the hose adapter, suction handpiece and suction cannula - collector with its cover, splash guard and handle. Risk assessment and classification The VC 45 is a medical product that comes into contact with blood and internal tissues. In the Federal Republic of Germany, for example, a risk evaluation must be carried out and medical products used in dentistry are to be categorised prior to preparation according to the "Recommendations of the Commission on Hospital Hygiene and the Prevention of Infections". - Collector with its cover, splash guard and handle, suction hose with hose adapter, suction handpiece and suction cannula: "Semicritical B" with the increased requirements to the preparation in each case The instructions described below have been validated by Dürr Dental as suitable and are recommended for the preparation of VC 45 components before and after use. The surgery manager is responsible for ensuring that the correct and safe preparation of the instruments is carried out using suitable appliances, materials and trained personnel in order to produce the desired results.validation and routine monitoring of the preparation procedures are necessary.any and every deviation from the procedures described below by preparation staff is solely the responsibility of the personnel in terms of effectivity and the possible negative repercussions. Preparation process The preparation process (disinfection, cleaning, sterilisation and storage) of the VC 45 components after every use is in accordance with the preparation information according to ISO Pre-cleaning and disinfection Before removing the collector vessel, the suction hose should be disinfected.draw up approx.0.5 l disinfectant (e.g.orotol Plus or another agent specifically approved by Dürr Dental) and allow sufficient time to work. Observe the max. level permitted in the collector. Remove the suction hose with the hose adapter piece out of the collector lid using a slight twisting motion.finally, take the complete suction hose apart. 2013/10 21

Release the engaging catches of the handle to the collector.pull the two catches outwards so they are no longer holding onto the sides of the cover and pull the handle carefully upwards.remove the bacteria filter/excess vacuum stop from the handle section. Use both hands to remove the lid from the collector.remove the spray guard. Dispose of the contents of the collector as appropriate Disinfection and cleaning Use cleaning and disinfection devices strictly according to manufacturer's instructions. Place the individual parts into the unit in such a way that the interior surfaces will be rinsed thoroughly and the water can drain off. Set up the cleaning and disinfection cycles according to the manufacturer s instructions. After the cleaning and disinfection cycles have finished, carefully check the individual parts for signs of residual dirt and repeat the cycles if necessary /10

23 Steam sterilising Individual parts can be sterilised either unpacked or packed in a container or in sterile product packaging.use suitable sterile product packaging. Warning Incorrect sterilisation inhibits effectiveness and can damage the product Only steam sterilisation is permitted. Do not exceed 134 C. Observe the process parameters. Do not use any other procedures. Place filter paper on the sterilisation tray. Always sterilise the parts for sterilisation together with instruments, as this ensures even temperature distribution. Avoid any metal contact of the parts for sterilisation with either any other instruments or with the sides of the tray. Place parts for sterilisation away from the heating rods and on the middle rack so there is no contact with the inside walls of the system. The product must be sterilised in a disassembled state only. 34 Temperature: 134 C Pressure above the ambient surroundings: 2.16 bar / MPa Working time: 5 min Parts for sterilisation must be placed in a small steam steriliser before every use in accordance with and with sterilisation cycle Type B with subsequent drying. Carefully observe the manufacturer s instructions regarding usage of the steam steriliser and the correct placement of parts to be sterilised. Observe all national and local guidelines and standards regarding the sterilisation of medical products. 2013/10 23

24 16.5 Checking and testing the functioning Frequent reprocessing in this way can have a slight effect on plastic and rubber parts, such as collector, collector lid, handle and suction hose. The end of the product's life cycle is determined by the amount of wear and tear or damage during use.always check plastic and rubber parts and replace where necessary, disposing of damaged parts as appropriate.before disposal, the parts should be disinfected and sterilised Storage Store individual parts protected against contamination Disinfection and cleaning of the appliance surfaces Before disinfection and cleaning of the appliance, unplug at the mains and remove all power. Always clean the surfaces using a damp cloth. Do not use a dry cloth. In the case of coarse organic contamination, pre-clean with cellulose. As a surface disinfectant, we recommend a material compatible disinfectant in accordance with the usual dental health standards, e.g.dürr Dental FD 322, FD 366 or FD 350 disinfection wipes /10

25 17. Maintenance 36 The bacteria filter/excess suction stop (15) is only to be used once and must be changed at least once a day. If the appliance is to be used continuously for longer periods (several hours), it is important to change the bacteria filter after each patient. Never operate the appliance without bacteria filter/excess vacuum stop. Only use original Dürr bacteria filters. Before every application, carry out a visual check of the appliance including hoses, handpiece and collector.if the collector, its cover or its handle section show signs of wear, such as minute cracks, these parts should be replaced Fuse changing Before replacing the fuse, remove the plug and the connector on the bottom of the appliance. Use a small screwdriver to disengage the spring clips on each side of the fuse by pressing carefully and pull the fuse out. Insert a new fuse and replace the holder until both clips engage again. Connect to the mains cable again /10 25
